I have a "camping cat". I'm a second generation boxy owner as my son got his Jan 03 and I followed Dec 03. I have over 10k miles on my "camper" but the cat that rides with me claims 9k of that. - from Ky to AZ and back and then to Virginia Beech and back. He is 6 months old, travels in a small kennel, is leash trained, and eats,drinks, walks, and uses his litterbox at rest areas just like everybody else. His stopping schedule basically matched mine. Camping at nite he has an open litterbox and the run of the car. When warm weather comes my challenge will be to give him range yet have windows screened for air circulation. So far I have used cardboard window inserts with screen panels. Any ideas?
